Coval Multi Purpose Sealer is an invisible, breathable high-performance sealer

It is designed to be extremely water-repellent, stain and mold-resistant on almost any substrate including concrete, slate, unmodified grout, brick, tile and both natural and artificial stone. It will not change the appearance of the underlying surface.

Coval Multi Purpose Sealer uses next generation technology and is completely different from other penetrating sealers. This is because in Coval products molecules cross-link to form a covalent bond with the surface.   This creates a superior barrier against moisture.

Coval Multi Purpose Sealer is an environmentally smart product that has zero VOCs and contains no known carcinogens. Its use will not harm soil or plants. Coval Molecular is so easy to apply.  You won’t leave roller marks and you can stand on it when its wet and you won’t leave footprints. Dry-time is typically 1 hour, but the re-application time is only 10-15 minutes.  No stripping is required before re-application.

Not only this but Coval Multi Purpose Sealer lasts longer than traditional sealers so it offers a very cost-effective protection against moisture, stains, ice, dirt and mold.

Use it on historic buildings and on surfaces where it’s important that the protection is invisible.

Tough, durable, environmentally sound and free of carcinogens

With zero VOCs it outperforms the most stringent air-quality controls in the US. Coval also measures as being carcinogen free as defined by California Prop 65.
